Help creating a while loop

[rinnamorato]

Guys,

I wrote a program that search for substrings and prints the line starting with the substring to the end of the line. I need to add a loop that will continue to check for a occurence of the string until the complete line has been checked.

I wrote the program and also I was able to write a line that will check for the next occurence after the first but I can't figure out how to create a loop that will keep going until the entire line of text has been checked.

here is the code I have:

#include <iostream>
#include <string>
#include <cstring>
#include <cstdio>
#include <cstdlib>


using namespace std;

int main()
{

	char firststring[80];
	char search [80];

	char *searchPtr;
	char *searchPtr2;

	cout << "Enter the first sentence: " << endl;
	cin.getline(firststring, 80, '\n');

	cout << "Enter the string you are looking for: " << endl;
	cin.getline(search, 80, '\n');

	searchPtr = strstr(firststring, search);

	cout << "String1 = " << firststring << "\nstring2 = " << search
		 << "\n\nThe remainder of string1 beginning with the\n"
		 << "first occurrence of string2 is: \n"
		 << searchPtr << endl;

//I need the while loop here

		cout << "There is another occurrence of the search string that starts here: \n"
			 << strstr(searchPtr + 1, search) << endl;

	return 0;

}

I using a couple of arrays so I tried to create a while loop using the size of the array but my array is 80 and the while loop keeps printing out the same last line 80 times.

Any advice?

A for loop would be easier to use to traverse an array.
